In recent years, the integration of medical science with engineering and technology has become increasingly vital, especially in treating complex congenital heart diseases. In China, conditions such as single-ventricular and complex linear heart defects remain challenging to cure. To achieve a more effective and lasting treatment, doctors now rely on advanced techniques like computer simulations and 3D printing. These innovations allow for personalized surgical planning, ensuring better outcomes for patients.
On the afternoon of October 22, in the conference room of Wuxi Mingci Cardiovascular Hospital, researchers from Georgia Institute of Technology, Nanjing Medical University, and the Jinan Military Region gathered to observe a live surgery. This particular Fontan procedure was unique, as it involved not only top cardiovascular experts but also scientists and engineers from various fields. By combining computational fluid dynamics (CFD), medical imaging, and virtual simulation, they were able to design a tailored surgical plan for each patient.
Fontan surgery is a critical procedure for children with complex congenital heart conditions that cannot be fully corrected through traditional methods. Historically, surgeons used invasive techniques that often led to significant trauma and complications. However, after over 30 years of research, Professor Qiao Bin’s team introduced a new approach using CFD-based virtual modeling. Before the operation, detailed patient data was collected and analyzed through advanced hydrodynamic simulations. Based on these models, a customized surgical plan was created, enabling precise and effective treatment.
Guo Xirong, deputy dean of the Institute of Translational Medicine at Nanjing Medical University, emphasized the importance of merging medical science with engineering. She pointed out that many complex congenital heart diseases in China still lack a definitive cure. To address this, doctors must conduct detailed imaging studies, simulate surgeries on computers, and even use 3D printing to create custom implants. Since a child’s heart continues to grow, any implanted devices must accommodate future development. Thanks to computerized pre-surgical planning, it's now possible to perform radical treatments that significantly improve quality of life. This groundbreaking integration of fluid mechanics and medicine marks a major advancement in the field, offering hope where there was once little.
